Need to disable & enable a hardware device.

I searched, but only a post from 2011 -- using devcon.exe, the only '64 bit' version is for Itanium, the 32bit seems to fail for me.

My laptop, the aggravating pos that it is, if the laptop suspends or hibernates -- I cannot get back on the network. I only have two choices: reboot (easy/slow) or disable the hardware device for wifi, re-enable, connect (cumbersome, fast). w/o using autoitscript, I'm hoping there's a way (batch file, or programmatically, which is preferred) to automate this so I can just click on an short cut and have it all done for me.

Devcon (32bit) fails to disable the device. (docs say it doesn't do everything on x64), and the api's I've found (DeviceProperties,DevicePropertiesEx,&DeviceAdvancedProperties) all seem to be undocumented.

Does anyone have a tip to get it done?

Hi jassing,

here an example that enable disable Network adapters over WMI ComatePlus is needed.

You can obtain the Windows 7 or 8 version of devcon including source code in the Windows Driver Kit
I copied mine to the system32 folder so I can access it easily from the command line.
The C++ source code should help to understand the api's.

Path of the installed Windows 8 version
C:\Program Files (x86)\Windows Kits\8.0\Tools\x64\devcon.exe

Windows Driver Kit (WDK)
http://msdn.microsoft.com/en-us/windows ... 87428.aspx
Devcon (32bit) fails to disable the device. (docs say it doesn't do everything on x64), and the api's I've found (DeviceProperties,DevicePropertiesEx,&DeviceAdvancedProperties) all seem to be undocumented.
Does anyone have a tip to get it done?
1.) Find network adapter
devcon hwids =Net
(example yours will differ)

Code: Select all

PCI\VEN_8086&DEV_1503&SUBSYS_849C1043&REV_04\3&11583659&0&C8
    Name: Intel(R) 82579V Gigabit Network Connection
2.) Find a unique section of the string and test that only the network adapter will be disabled.
devcon find *DEV_1503

Code: Select all

here an example that enable disable Network adapters over WMI ComatePlus is needed.
Well; I tried the code "as is" (fixing some duplicate structure definitions, and native pointer types):
On x64 it worked w/o an issue
on x86 (two systems) and I get an IMA on:

Code: Select all

SetGadgetItemText(#Listview_0,x2,ConfigNet()\MACAddress,3)
What's odd is if I do a debug line, the address prints out ok. tested pb 5.11 and pb5.2

sure that you use the actually ComatePlus Version?
I have now installed 5.20 b5 and not need change somethings on the Comateplus include for use the sample. strange ....

on my test with XP SP3 when listing the adapter occure an IMA.
this can fixed, change the line on the procedure GetStringformVariant

Code: Select all

yes, absolutely, how would it have gotten that far if it couldn't include the commateplus files?

Trying this code on WinXP with PB5.30 but I get a compiler error at this ComatePlus procedure:

Code: Select all

Procedure.i COMate_INTERNAL_PrepareStatement(command$, *ptrStatement.INTEGER)
  Protected errorCode = #S_OK, *hStatement._COMatePLUSStatement
  Protected Dim parse._COMateParse(#COMate_MAXNUMSUBOBJECTS), i, subObject
  If command$
    ;Allocate memory for a statement handle.
      *hStatement = AllocateMemory(SizeOf(_COMatePLUSStatement))
    If *hStatement
      ;Tokenise the command string.
        *hStatement\numSubObjects = COMatePLUS_TokeniseCommand(command$, "(),\'= ", parse())
        If *hStatement\numSubObjects
          For subObject = 1 To *hStatement\numSubObjects
            ;We need to parse/compile the tokenised command corresponding to each individual sub-object.
              errorCode = COMatePLUS_CompileSubobjectInvokation(*hStatement, subObject, @parse())
              If errorCode <> #S_OK
                COMate_FreeStatementHandle(*hStatement)
                Break

          Next

EndProcedure
